TO ALL WHOM IT MAY CONOERN:

Be -it known that I, MORTIMB. S. IIARSHA, in the town of Batavia, in the county of Kane, and State of Illinois, have invented a new and useful Improvement in Goncrete-Brick Machines ;A and I do hereby declare that the following is a full, clear, and exact description of -the same, reference being hadl'to the accompanying drawings, and the letters and igures marked thereon, .in which Figure 1 represents a top or plan view, A

Figure 2 a side elevation, and

Figure 3 a vertical sectional view of my invention.

To enable those skilled inl the art to understand howto manufacture and-use my invention, vI will proceed to describe the same with particularity.l y

There is a solid frame, A, made ofany suitable material, onwhich is constructed amould, B. The top of the mould is composedof a sliding piece, D, and the front of a sliding piece, C, both of which slide in grooves in the stationary side pieces H. There is' a'. follower, E, in the rear of the mould, behind which, andoperating the same, is the knee-jointed pieceI. The rear end of this knee-jointed piece I turns on stationary-trunnions J; ,and the front end has trunnions, which slide in grooves in the side pieces H behind the follower There is a weightrK, attached to the piece lI for the purpose of throwing it'in the position shown in figs. 1 and 2; or there may be a spring, L, placed beneath said piece to accomplish the same result. There is also a shaft, M, extending across the frame A, beneath the vpiece I, to one end of which there is attached a crank'orgearing for turning the same; and to the .said shaft there is attached one end of a chain or rope, r, the other end of which is attached to the jointed piece I, as clearly shown in iig. 3. There is a lever, F, which extends throughthe side piece H, and is so connected with .the follower E as to enable the operator with it to slide said follower E back and forth in the hopper B. The connection of the lever F with the follower E is effected by means of a y pin, e, projecting downward from the follower or plunger E, which the fork upon the 'end of 4the lever strides, as indicated in dotted lines in fig; 1; but it may be eifected in 'any other suitable manner. The sliding end piece C of the hopper is held up in the position shown in iig. 3 by the spring N, and-is operated, as hereinafter described, either bythe operator taking hold ofthe end of the spring and bearing it down, or by the operator placing his foot on the treadle O, which is 'attached at its vibrating end to the sliding piece C by means of the rod P, and pressing it down. The top s ide pieces of the frameA extend out in front of the mould B, as shown at Q, so as to admit of a board, R, being placed thereon to receive the brick as it is forced outof the hopper B, as hereafter described. S is a suitable platform attached to the side of the mould, upon which the preparedV material is placed convenient for filling the mould as desired.

Having thus described the construction-of my machine, I will now describe the operation of the same. The operator slides back the top piece D, and, after filling the mould B with material, slides it forward again over the mould. He then takes hold of the crank, and, by winding'the chain on the shaft M, straightens the `iointed piece I, and thereby forces it against the follower E, and presses the brick with great power. The end piece I) is then thrown down, when the operator takes hold of the lever F, and slides the pressed brick out upon the board R. This being done, the follower E is thrown back, and the end piece D allowed to slide-up. The pressure on the brick may be increased to any extent by attaching gearing to the shaft M.

Having described the construction ,and operation o f my invention, what I claim, and'desire to secure by Letters Patent, is-

1. The combination of the mould, composed of the slides D C, and thebottom X, tbe-plunger E, an'l the jointed lever I, all arranged substantially in the manner and for the purposes set forth.

2. I claim thc Combination of the mould, constructed of the bottom X and the slides C and D, with the jointed arm I, shaft M, cord r, and spring L, or its equivalent, arranged and operating as and for the purposes specified. l* l r A l 3. I claim the combination of the mould, slides D and C, spring N, plunger E, and lever F, arranged and operating as and for the purposes set forth.
